西宁曹家堡国际机场T3航站楼季节性停航给排水系统应对措施探讨

中国化学会第九届全国无机化学学术会议

Synthesis of biaryl compounds through C-H bond activation of arylation has been the focus and frontier research in the field of green chemistry and Pharmaceutical Synthesis. TAraditional homogeneous catalysts has made great achievements in this field. However, there are many issue to resolve, such as the large amount of catalysts dose, recycle problem of catalysts, and product isolation problems. Moreover, the catalytic process generally requires relatively harsh dry environments, which increases the cost of large-scale synthesis and causes environmental pollution. We succeeded in synthesizing uniformly dispersed Pd nanocomposite with sub-5 nm in size by using cucurbit[n]uril as a carrier via a simple one-pot method. With significantly noble metal loading, such nanocomposite showed high activity towards C-H bond activation with satisfactory yields of the product. The catalytic procedure was safe to air and moisture. Importantly, the developed catalytic system can be effectively recycled multiple times without obvious loss of activity with a broad range of substrates, demonstrating a good efficiency and selectivity. The research group also studied the effect of different type of cucurbit[n]uril（n=5-8） on the structure of Pd nanocomposite as well as the corresponding catalytic performance. The heterogeneous catalytic mechanism of the C-H bond activation was also verified by experimental data.

随着经济的快速发展以及旅游消费的井喷式增长,西宁曹家堡国际机场航空业务量快速增长,旅客吞吐量逐年大幅攀升,然而受当地气候条件的影响,每年的淡季(11月至次年5月)和旺季(6月至10月)机场的客流量差异悬殊,给机场的运行管理系统和能源管控系统带来了巨大的挑战,为节省航站楼运行费用和节约能源,机场管理部门提出航站楼局部区域淡季停航的想法。针对西宁曹家堡国际机场季节性区域停航,分析和探讨航站楼内给排水及消防系统应对此问题的策略和措施,达到淡、旺季给排水及消防系统既能安全运行,又能节约能源的目的。

党的十九大报告提出“人民有信仰,国家有力量,民族有希望”,要构筑中国精神,为人民提供精神指引。中国精神是马克思主义与中华优秀文化融通的精神结晶、社会主义核心价值观的精神底色、中国共产党领导人民实现中国梦的精神倡导,具备指引人民信仰的思想指南、价值导向、政治保障三重优势。目前中国精神在指引人民信仰上的蕴涵梳理与阐发供给,还存在不适应信仰形成阶段性发展需求、不适应信仰双重功能作用发挥需求、不适应信仰主体阶层差异需求三组矛盾。解构信仰的神化、物化与虚化,须从以求真精神指引心性生命重返人心自由、以尚善精神指引德性生命重建人格高贵、以审美精神指引灵性生命重炼人品纯良三个维度,寻求中国精神指引新信仰形态生成的路径突破。

[Objective] This study aimed to establish a quantitative real-time PCR （qRT-PCR） system for detecting the expression of rice beta-glucosidase gene Os1bglu4.[Method] The PCR was conducted with SYBR Green Ⅰ method,using the primers of reference gene actin or ubiquitin.[Result] Actin was more suitable to be the reference gene than *** accurate results were obtained when the 100 ng cDNA template was added at a large volume and a lower *** primer concentration in the range from 0.2 to 0.8 μmol/L we set had no significant influence on the results,so,0.4 μmol/L was selected as the optimal primer concentration in this *** amplification efficiency was greatly reduced when the annealing temperature was set at 64 ℃,therefore,annealing temperature was set at 60 ℃.Compared with the reaction system of 25 μl,the fluorescence intensity was significantly lower but the CT value did not change greatly in 10 μl ***,the 10 μl reaction system was selected,which significantly reduces the research costs for the detection of a large amount of samples in future study.

The characteristics of zinc finger of Kruppel homolog-1 （N/kr-hl） gene from brown planthopper and its effect on expression of FAMET and JHE were studied in the paper, in order to understand the regulation role of Nlkr-hl. The evolutionary tree of each zinc finger in functional area of Nlkr-hl was analyzed via MEGAS. 0 software, and expression status of FAMeT and JHE after interference of N/kr-hl was determined using qPCR technology. The results showed that the functional area of N/kr-hl mainly included eight zinc fingers, and the conservativeness of Znl and Zn8 was relatively lower. In the brown planthopper with N/b＇-hl gene knockout, the expression levels of FAMeT and JHE increased. The paper provided the theoretical basis for understanding molecular mechanism of juvenile hormone signaling pathway and biological control of brown planthopper.

为了研究HFW焊接接头在载荷作用下的微观变形特点,利用扫描电镜下的原位拉伸试验对其变形过程进行了观察。在拉伸过程中试样变形主要集中在热影响区,裂纹在热影响区形核,并垂直于拉伸方向扩展,直至试样断裂。HFW焊接接头的断裂为延性断裂,裂纹呈穿晶型。其变形及开裂过程包括:试样弹性伸长、晶内滑移开动、试样缩颈变形和试样开裂。在拉伸作用下,滑移变形不断积累是造成裂纹形成及试样断裂的主要原因。
